摘　　要：以水杨醛、对甲氧基苯甲酸为起始原料,通过溶剂热法经酯化、肼化及希夫碱缩合合成了水杨醛对甲氧基苯甲酰腙,以六水合硝酸镨(Pr(NO_3)_3·6H_20)为原料,合成了水杨醛对甲氧基苯甲酰腙-Pr配合物荧光粉,经元素分析、核磁及X射线单晶衍射等分析手段对产物进行表征,采用荧光分光光度计测得该类配合物的荧光性能,结果表明,该目标产物可被470nm蓝光激发,在617nm处有较好的红光发射。Acylhydrazones exhibit strong coordination ability,and act as promising organic intermediates attributed to the presence of both azomethine （C=N） and carbonyl （C=O） groups, ligand were synthesized using salicylaldehyde and benzoic acid derivatives as raw materials by integration of esterification, hydrazine,and schiff base. Series of praseodymium rare earth complexes with salicylaldehyde hydrazone were then synthesized using the as-prepared four types of ligands and Pr（NO3）3. The molecular structures of complexes were inferred by elemental analysis, thermogravimetric analysis, and oth- er analytical methods. The fluorescence properties of complexes were measured by spectrophotometer. The results showed that complexes could be excited by 470nm blue light,with a good red light emission at 617nm.
